[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1 - Figure 3This utility model provides an embodiment of a pressing device for three-dimensional digital printing, comprising a base 1, a rotating platform 2 rotatably connected to the surface of the base 1, the rotating platform 2 providing a platform for rotation to prevent the printed product from being printed. A bracket 3 is fixedly connected to the surface of the base 1, and a pressing component 4 is provided on the bottom surface of the bracket 3. The bracket 3 supports the pressing component 4 so that the pressing component 4 is located directly above the rotating platform 2.

[0036] Reference Figure 1 - Figure 2 The clamping assembly 4 includes a C-shaped plate 41, which is rotatably connected to the bottom surface of the bracket 3. Two sets of symmetrically arranged movable seats 42 are slidably connected to the bottom surface of the C-shaped plate 41. The two sets of movable seats 42 are threadedly connected to each other by a bidirectional threaded rod 43. The end of the bidirectional threaded rod 43 is rotatably connected to the inner wall of the C-shaped plate 41. The bidirectional threaded rod 43 is used to drive the two sets of movable seats 42 to move towards each other or away from each other along the bottom surface of the C-shaped plate 41. A motor 44 is fixedly connected to the side wall of the C-shaped plate 41. The output shaft of the motor 44 is rotatably connected to the inner wall of the C-shaped plate 41. The output shaft of the motor 44 is fixedly connected to the end of the bidirectional threaded rod 43. A horizontal plate 45 is fixedly connected to the bottom surface of the movable seat 42. The motor 44 provides the power for the rotation of the bidirectional threaded rod 43 through its output shaft.

[0037] Reference Figure 1 - Figure 2 The bottom surface of the horizontal plate 45 has a groove 46. Two sets of symmetrically arranged sliders 47 are slidably connected inside the groove 46. The horizontal plate 45 moves synchronously with the movable seat 42, allowing the distance between the two sets of horizontal plates 45 to be adjusted. The groove 46 provides a track for the movement of the two sets of sliders 47. The two sets of sliders 47 are threaded together by a double-threaded rod 48. A motor 49 is fixedly connected to the end of the horizontal plate 45. The output shaft of the motor 49 passes through and is rotatably connected to the inner wall of the groove 46. The output shaft of the motor 49 is fixedly connected to the end of the double-threaded rod 48. The motor 49 drives the double-threaded rod 48 to rotate through its output shaft, thereby causing the two sets of sliders 47 to move towards each other or away from each other, adjusting the distance between the two sets of sliders 47.

[0038] Reference Figure 1 - Figure 2An electric telescopic rod 410 is fixedly connected to the bottom of the slider 47, and a pressure plate 411 is fixedly connected to the bottom surface of the electric telescopic rod 410. The slider 47 drives the electric telescopic rod 410 to move synchronously, which in turn drives the pressure plate 411 to move downward, pressing the product onto the surface of the rotary table 2. A motor 412 is fixedly connected to the surface of the bracket 3. The output shaft of the motor 412 passes through and is rotatably connected to the bottom surface of the bracket 3. The output shaft of the motor 412 is fixedly connected to the C-shaped plate 41. The motor 412 drives the C-shaped plate 41 to rotate, causing the entire pressing assembly 4 to rotate, along with the pressed product and the rotary table 2, thus ensuring that the product is dried evenly.

[0039] Reference Figure 1 , Figure 2 A positioning component 5 is provided on the surface of the rotary table 2. The positioning component 5 is used to position the product placed on the surface of the rotary table 2. The positioning component 5 includes a movable groove 51, which is formed on the surface of the rotary table 2. A support plate 52 is slidably connected inside the movable groove 51. A V-shaped plate 53 is fixedly connected to the side wall of the support plate 52. The support plate 52 is elastically connected to the inner wall of the movable groove 51 by a return spring 54. The movable groove 51 provides a track for the support plate 52 to move. The return spring 54 provides elastic support for the support plate 52, so that the support plate 52 drives the V-shaped plate 53 to fit against the side wall of the product for positioning. A through hole is formed in the side wall of the support plate 52, and a guide rod 55 is slidably connected in the through hole. The end of the guide rod 55 is fixedly connected to the inner wall of the movable groove 51. The guide rod 55 is used to position and guide the support plate 52, so that the support plate 52 moves stably inside the movable groove 51.

[0040] Working principle: When the product is placed on the surface of the rotary table 2, the support plate 52 and its V-shaped plate 53 move together under the elastic force of the return spring 54, fitting against the side of the product for positioning. The guide rod 55 ensures that the support plate 52 moves smoothly and stably within the movable groove 51.

[0041] Motor 1 drives the bidirectional threaded rod 43 to rotate via its output shaft, thereby controlling the two sets of movable seats 42 to move towards or away from each other, thus adjusting the distance between the horizontal plates 45. The output shaft of motor 2 49 is fixedly connected to the end of the bidirectional threaded rod 48. Motor 2 49 drives the bidirectional threaded rod 48 to rotate via its output shaft, thereby causing the two sets of sliders 47 to move towards or away from each other, thus adjusting the distance between the four sets of pressure plates 411 according to the size of the product.

[0042] The electric telescopic rod 410 drives the pressure plate 411 to press down, thereby completing the pressing of the product surface. The motor 412 drives the C-shaped plate 41 to rotate, so that the entire pressing assembly 4 drives the pressed product and the rotating table 2 to rotate, so that the product can be dried evenly.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
